Thanks.
Your example helped .. At least now I can see how it might be done.
if it really was required.
I'm thinking now though that I was abusing the dispatch table, trying
to get more done that could be better done other ways. First by
letting the functions called in the table work on global information,
instead of trying to pass it through the table.
Philip P.s' explanation and now your example of how to do something
like that using the `closure' approach, made me see I was going at it
a bit wrong to start with.
